Allowing includegraphics in LaTeX to include files with arbitrary filenames

Question

I have some graphic files with some rather long filenames which includes several periods. includegraphics interprets the first of these as the beginning of the file extension, which makes it impossible for it to guess the proper graphics extension. A typical error message is

LaTeX Error: Unknown graphics extension: .9332.1dwc_kpl_h.log.png

One solution is to rename all files, but they are generated by another program, and I would rather use the naming scheme from there. Is there a way to tell graphics what the image format is, such that the extension will be ignored?

Answer 1

You can also hide the dots from LaTeX by putting extra curly braces in:

\includegraphics{{my.file.with.dots.in.it}.png}

(from https://tex.stackexchange.com/questions/10574/includegraphics-dots-in-filename)

Answer 2

Use the grffile package.
